[Data for the establishment of maximum allowable concentration of chlorophenoxypinacoline in the working zone air]

Chlorophenoxypinacoline with its acute intragastric toxicity LD50 can be attributed to the 3rd class compounds of hazardousness (moderate hazardous substances). Local irritation and skin resorption effects were not revealed. Irritation of the mucous in the eyes in rabbits was moderate and functional cumulation was insignificant. Average lethal concentration (LC50) was not attained. The threshold of acute inhalation and irritation action (Limac, Limir) was at 1093 mg/m3, the threshold of chronic inhalation action (Limch) was at 165.2 mg/m3. No signs of specific mutagenic and embryotropic action were found. The accepted MAC for chlorophenoxypinacoline in the working zone air is 10 mg/m3. The aggregate condition aerosol, 3rd degree of hazardousness.
